The '''Diamond DA42 Twin Star''' is a four seat, twin engine, propeller-driven [[airplane]] developed and manufactured in [[Austria]] and [[Canada]] by [[Diamond Aircraft Industries]], an Austrian subsidiary of China-based [[Wanfeng Aviation]].<ref>[https://www.diamondaircraft.com/en/about-diamond/newsroom/news/article/new-owner-great-plans-for-diamond-aircraft/ "New Owner: Great Plans for Diamond Aircraft"]</ref> It was Diamond's first twin engine design, as well as the first new European twin-engine aircraft in its category to be developed in over 25 years.<ref name = "col spark">Collins, Peter. [https://www.flightglobal.com/news/articles/flight-test-diamond-aircraft-da42-sparkling-perfo-184208/ "FLIGHT TEST: Diamond Aircraft DA42 – Sparkling performer."] {{Webarchive|url=https://web.archive.org/web/20170423064458/https://www.flightglobal.com/news/articles/flight-test-diamond-aircraft-da42-sparkling-perfo-184208/ |date=2017-04-23 }} ''Flight International'', 13 July 2004.</ref> In 2004, the DA42 became the first diesel-powered fixed-wing aircraft to perform a non-stop crossing of the [[Atlantic Ocean|North Atlantic]].

By 2012, the DA42 had become a key revenue generator for the company, having gained popularity with government and military operators in addition to the civil market that had suffered as a result of the [[Great Recession]]. Government customers have typically employed the type in the [[surveillance|aerial surveillance]] role, which contributed towards the development of the [[Aeronautics Defense Dominator]], a [[medium-altitude long-endurance unmanned aerial vehicle|medium-altitude long-endurance]] (MALE) [[unmanned aerial vehicle]] (UAV), which had been derived from the DA42.

==Development==
===Origins===
Since its founding in the 1980s, [[Austria]]n manufacturer [[Diamond Aircraft Industries]] had concentrated on building an extensive product line. During the late 1990s, company founder and chief executive officer Christian Dries approached the design team with a concept for a twin-engined aircraft, which became the company's first multi-engined aircraft, and became the next step beyond the [[Diamond DA40]].<ref name = "fly mag 2015">
Pope, Stephen. [http://www.flyingmag.com/we-fly-diamond-da62 "We Fly: Diamond DA62."] {{Webarchive|url=https://web.archive.org/web/20170504233234/http://www.flyingmag.com/we-fly-diamond-da62 |date=2017-05-04 }} ''Flying Magazine'', 2 December 2015.
</ref> This concept emphasised several key qualities, including the need for the aircraft to be  simple to operate and fuel-efficient, while providing a luxurious four-seat passenger compartment akin to modern automobiles. The concept was not popular at the time; Aerospace publication [[Flying Magazine]] referred to Diamond's choice to develop a twin-engined aircraft for [[general aviation]] use as "the emergence of an all-new light-piston twin in this class something of a surprise."<ref name = "fly mag 2015"/>

[[File:diamond da42 twin star hb-sdm riat 2010 arp.jpg|thumb|right|The DA42 Twin Star]]
During April 2004, the DA42 Twin Star received certification from the [[European Aviation Safety Agency]] (EASA) under the latter's newly-introduced Part procedures.<ref>{{cite web |url = http://www.diamondair.com/news/05_13_04.php |title = DA42 Twin Star EASA certification |publisher = Diamond Aircraft |date = May 2004 |url-status = dead |archive-url = https://web.archive.org/web/20080421220543/http://www.diamondair.com/news/05_13_04.php |archive-date = 2008-04-21 }}</ref><ref name = "col spark"/> In July 2005, the aircraft was awarded certification from the [[Federal Aviation Administration]] (FAA) in the US.<ref>{{cite web |url = http://www.diamondair.com/news/07_26_05.php |title = DA42-TDI Twin Star FAA certified |publisher = Diamond Aircraft |date = July 2005 |url-status = dead |archive-url = https://web.archive.org/web/20080511074624/http://www.diamondair.com/news/07_26_05.php |archive-date = 2008-05-11 }}</ref> It has been certified to fly under both [[visual flight rules]] (VFR) and [[instrument flight rules]] (IFR), allowing it to be operated under a wide range of conditions. At the time of its introduction to service, aerospace publication [[Flight International]] observed that "The DA42 has no natural competitors in its class and sets a benchmark for European general aviation".<ref name = "col spark"/>

During August 2004, the DA42 Twin Star piloted by [[Gérard Guillaumaud]] became the first diesel-powered [[fixed-wing aircraft]] to perform a non-stop crossing of the North Atlantic, taking 12.5 hours while operating with an average fuel consumption of {{convert|21.73|litre}} per hour ({{convert|10.86|litre}} per hour per engine).<ref>{{cite web |url=http://www.diamondair.com/news/08_20_04.php |title=DA42 Twin Star crosses Atlantic non-stop: first Atlantic crossing of a diesel powered aircraft |access-date=14 April 2008 |last=Diamond Aircraft |year=2004 |archive-url=https://web.archive.org/web/20080331041108/http://www.diamondair.com/news/08_20_04.php |archive-date=31 March 2008 |url-status=dead }}</ref> In June 2010, a DA42 powered by [[Austro AE300]] engines became the first aircraft to be publicly flown on [[algae]]-derived jet fuel.<ref name="AvWeb09Jun10">{{cite web |url = http://www.avweb.com/avwebflash/news/algae_fuel_diamond_da42_berlin_efficient_202700-1.html |title = EADS: Algae-Fueled DA42 A "World's First" (And Better) |access-date = 10 June 2010 |last = Pew |first = Glenn |date = June 2010 |archive-url = https://web.archive.org/web/20110611225341/http://www.avweb.com/avwebflash/news/algae_fuel_diamond_da42_berlin_efficient_202700-1.html |archive-date = 11 June 2011 |url-status = live |df = dmy-all }}</ref>

===Further development===
As a consequence of the [[insolvent|insolvency]] of engine manufacturer Thielert and decisions of the insolvency administrator, including cancelling warranty support and the prorating of time-between-overhaul for the Thielert engines that power the DA42, in July 2008, Diamond announced that production of the DA42 had been suspended. At the time production was suspended the DA42 was reported to hold around 80% of the piston twin market.<ref name="AvWeb16Mar09" /><ref name="Avweb26Jul08">{{cite web |url = http://www.avweb.com/avwebflash/news/DiamondTriesToSootheDA42Customers_198391-1.html |title = Diamond Tries To Soothe DA42 Customers |access-date = 28 May 2008 |last = Niles |first = Russ |date = July 2008 |archive-url = https://web.archive.org/web/20090107093937/http://www.avweb.com/avwebflash/news/DiamondTriesToSootheDA42Customers_198391-1.html |archive-date = 7 January 2009 |url-status = live |df = dmy-all }}</ref><ref name="AvWeb06Nov08">{{cite web |url = http://www.avweb.com/news/aopa/AOPAExpo2008_Diamond_ThielertDieselEngine_Relief_199144-1.html |title = Diamond's Thielert Problems Ease |access-date = 7 November 2008 |last = Niles |first = Russ |date = November 2008 |archive-url = https://web.archive.org/web/20081112083022/http://www.avweb.com/news/aopa/AOPAExpo2008_Diamond_ThielertDieselEngine_Relief_199144-1.html |archive-date = 12 November 2008 |url-status = live |df = dmy-all }}</ref>

In March 2009, Diamond achieved EASA certification for the [[Austro Engine E4|Austro Engine AE 300]], which enabled the DA42 to resume production. Equipped with the Austro engine, these aircraft were designated and marketed as the ''DA42 NG''.<ref name="AvWeb16Mar09"/> In April 2009, the first Austro-powered DA42 NG was delivered to a customer in Sweden. On 9 April 2010, the DA42 NG received FAA certification, clearing the way for sales to resume to North American customers.<ref name="AvWeb16Mar09"/>

By March 2012, the DA42 had become the major income driver at Diamond Aircraft. Company CEO Christian Dries indicated that the market focus of the company had been changed by the [[Great Recession]] of 2008–2010 which had led the company to transition to derive two-thirds of its revenue from military and government contracts, primarily for manned and unmanned [[surveillance aircraft]], the latter in the form of the [[Aeronautics Defense Dominator]].<ref name="Bertorelli13Mar12A">{{cite news |url = http://www.avweb.com/blogs/insider/AvWebInsider_SensorTech_206312-1.html |title = Diamond's Commercial/Military Turn |access-date = 15 March 2012 |last = Bertorelli |first = Paul |date = 13 March 2012 |work = AVweb |archive-url = https://web.archive.org/web/20120316230847/http://www.avweb.com/blogs/insider/AvWebInsider_SensorTech_206312-1.html |archive-date = 16 March 2012 |url-status = live |df = dmy-all }}</ref>

Also in March 2012, Diamond aircraft announced they were developing a [[fly-by-wire]] version of the DA42, which had the stated aim of reducing the accident rate in light aircraft. The system is expected to include [[flight envelope protection]], turbulence righting, [[autoland]] capabilities, and damage-tolerant by-pass capabilities, the latter of which would allow for effective flight while suffering from jammed or otherwise non-functional flight surfaces.<ref name="Bertorelli13Mar12B">{{cite news |url = http://www.avweb.com/avwebflash/news/DiamondsDries_FlyByWireAsElectronicParachute_206315-1.html |title = Diamond's Dries: Fly By Wire As "Electronic Parachute" |access-date = 15 March 2012 |last = Bertorelli |first = Paul |date = 13 March 2012 |work = AVweb |archive-url = https://web.archive.org/web/20120316230810/http://www.avweb.com/avwebflash/news/DiamondsDries_FlyByWireAsElectronicParachute_206315-1.html |archive-date = 16 March 2012 |url-status = live |df = dmy-all }}</ref><ref name="Pew29Nov12">{{cite news |url = http://www.avweb.com/avwebflash/news/da42_flybywire_diamond_autonomous_control_pilot_207775-1.html |title = DA42 Fly By Wire Progress |access-date = 3 December 2012 |last = Pew |first = Glenn |date = 29 November 2012 |work = AVweb |archive-url = https://web.archive.org/web/20121207002743/http://www.avweb.com/avwebflash/news/da42_flybywire_diamond_autonomous_control_pilot_207775-1.html |archive-date = 7 December 2012 |url-status = live |df = dmy-all }}</ref> The autonomous DA42 was flown and landed without ground support in 2015.<ref name="Bertorelli-9sep15">{{cite news |url = http://www.avweb.com/avwebflash/news/Diamonds-Autonomous-DA42-Completes-Autolanding-Tests-224826-1.html |title = Diamond's Autonomous DA42 Completes Autolanding Tests |access-date = 9 September 2015 |last = Bertorelli |first = Paul |date = 8 September 2015 |work = AVweb |archive-url = https://web.archive.org/web/20150925095202/http://www.avweb.com/avwebflash/news/Diamonds-Autonomous-DA42-Completes-Autolanding-Tests-224826-1.html |archive-date = 25 September 2015 |url-status = live |df = dmy-all }}</ref><ref>{{youTube|RlaDeojkLcU|Diamond DA42 Autoland}}</ref>

==Design==
===Overview===
[[File:DA42Panel.JPG|thumb|Instrument panel of a DA42 Twin Star, note the installed [[Garmin]] [[G1000]] [[glass cockpit]] present]]
[[File:DiamondDA-42TwinStarN131TS04.jpg|thumb|right|A DA42 on static display; note the prominent [[Wingtip device|winglets]]]]
The Diamond DA42 Twin Star is a twin-engined low-wing [[cantilever]] [[monoplane]], commonly used as a [[general aviation]] aircraft for touring and training purposes.<ref name = "col spark"/> It is equipped with a retractable tricycle [[landing gear]] arrangement and uses a [[T-tail]]. The DA42 incorporates a combination of advanced features within the company's first twin-engine design.<ref name = "col spark"/> The airframe is composed of [[composite material]]s, making extensive use of [[carbon fiber reinforced polymer]]s throughout its structure; this construction provides the aircraft with a suitable passive safety level to conform with the established [[European Aviation Safety Agency]] (EASA) Part 21 rules, as well as relatively efficient aerodynamics and essentially unlimited airframe life.<ref name = "col spark"/> The carbon-fiber main wing spars possesses exceptional [[crashworthiness]].<ref name = "fly mag 2015"/>

The DA42 typically accommodates four people in two rows of seating.<ref name = "col spark"/> All of the seats have been designed for crashworthiness and are complete with automotive-style three-point seat belts; while the seats themselves are fixed in position, the position of the rudder-pedals is adjustable. The front pair of seats are accessed via a front-hinged canopy while a top-hinged door located on the left side provides access to the rear seats.<ref name = "col spark"/> The pilots are housed under a sizable canopy which provides generous external visibility, save for the use of a large fixed sunscreen. Additionally, separate baggage compartments, which are accessible via external hatches, are contained within internal space in the aircraft's nose.<ref name = "col spark"/><ref name = "fly mag 2015"/>

Both the avionics and principal flight controls of the DA42 have been designed to be user-friendly and to reduce pilot workload.<ref name = "col spark"/> A [[Garmin G1000]] [[glass cockpit]] serves as the centrepiece of the aircraft's integrated digital avionics, using a pair of large flat-panel monitors in place of conventional instrumentation and gauges; immediately above these monitors is a horizontal row of standby instruments present as a fail-safe.<ref>{{cite web |url=http://www.diamondair.com/news/04_28_03.php |title=Garmin's G1000 System offered in the DA42 Twin Star |access-date=15 April 2008 |last=Diamond Aircraft |year=2003 |archive-url=https://web.archive.org/web/20080511074609/http://www.diamondair.com/news/04_28_03.php |archive-date=11 May 2008 |url-status=dead }}</ref> The monitors display various information on the aircraft, along with navigational data and flight information; both screens can show identical basic information or be configured to flight data on the left monitor and navigation on the right.<ref name = "col spark"/> According to Flight International, the displays are easy to read while features such as the [[moving map display]] were considered to be "useful".<ref name = "col spark"/> The DA42 is also outfitted with a sophisticated three-axis [[Garmin]]-built GFC 700 [[autopilot]] and GWX 70 [[weather radar]].<ref name = "ft 2010"/><ref name = "fly mag 2015"/>

===Performance===
The flight performance of the DA42 is largely favourable, having been designed to incorporate not only high levels of performance but the greatest possible degrees of passive safety in operation, alongside  excellent fuel economy and assisted by the implementation of various modern technologies.<ref name = "col spark"/> The flight controls themselves are proportionally responsive for performing even small manoeuvers and light motions. Both pilots are equipped with their own fighter-style [[centre stick|central sticks]], which are attached to an otherwise unobstructed cockpit floor.<ref name = "col spark"/><ref name = "fly mag 2015"/> In a similar manner, a single combined power lever is used to regulate both the engine and propeller settings; the power levers are convenient and can be operated in a relatively easy manner. In comparison with other twin-engined aircraft in its category, the centre console of the DA42 is uncluttered, which is a result of the clean design of the controls.<ref name = "col spark"/><ref name = "fly mag 2015"/>

[[File:Diamond DA42 (8738055731).jpg|thumb|Underside of a DA42 passing overhead]]
The [[Stall (fluid mechanics)|stall]] characteristics are also relatively benign, being described by Flight International as "probably the most docile of any aircraft I can remember".<ref name = "col spark"/> On the DA42, stall conditions are forewarned by the sounding of a warning horn at {{convert|5|to|7|kn|km/h|0|abbr=on}} above stall, as well as by elevating levels of airframe buffeting and a 5–10° drop of the nose. The aircraft is relatively difficult to stall outside of substantial mishandling or deliberate intention.<ref name = "col spark"/> Both longitudinal and lateral stability can be maintained with a relatively low level of effort, not necessitating continuous [[trim tab|trimming]] while the aircraft is accelerating. Active use of the [[rudder]] is necessary for effective turns and counteracting [[sideslip]] tendencies.<ref name = "col spark"/>

While the DA42 is a twin-engined aircraft, this is predominantly a measure for safety.<ref name = "ft 2010"/> It is readily capable of sustained flight using only a single engine. DA42 NG climbs at up to 270 ft/min at sea level in standard conditions on a single engine, with performance degrading with higher altitudes and temperatures.<ref name="POH"/> The DA42 possesses considerable endurance, being capable of performing 13 hour-long flights without carrying additional fuel tanks; this is partially due to its high [[fuel efficiency]] of its Austro engines, which consume 13.6 US gallons per hour when operated at 75 per cent power, lower than some of its single-engined rivals.<ref name = "ft 2010"/><ref name = "fly mag 2015"/> The digital [[FADEC]] (full authority digital engine controls) serves to lower operational difficulty, constantly performing tasks such as managing [[Revolutions per minute|rpm]] and fault-checking.<ref name = "fly mag 2015"/> The propellers are clockwise-rotating as viewed by the pilot, so the left engine is the [[critical engine]].<ref name="POH">{{cite web|url= http://support.diamond-air.at/fileadmin/uploads/files/after_sales_support/DA42_New_Generation/Airplane_Flight_Manual_with_MAM42-600_DA42-VI/Basic_Manual/70116e-r5-complete.pdf|access-date= 10 October 2023|publisher= [[Diamond Aircraft]] |work= support.diamond-air.at|date= 29 April 2004|archive-url= https://web.archive.org/web/20230130234036/http://support.diamond-air.at/fileadmin/uploads/files/after_sales_support/DA42_New_Generation/Airplane_Flight_Manual_with_MAM42-600_DA42-VI/Basic_Manual/70116e-r5-complete.pdf|archive-date= 30 January 2023 | title = Airplane Flight Manual DA 42 NG }}</ref>

===Powerplants===
[[File:DiamondDA-42TwinStarN131TSThielertEngineDetail.jpg|thumb|Diamond DA42 Twin Star [[Thielert]] Centurion 1.7 diesel engine]]
The original model of the DA42 was powered by a pair of Thielert Aircraft Engines-built TAE 125-01 Centurion 1.7 engines. However, Thielert ended its production of the 1.7 litre Centurion engines in favour of a new 2.0 litre engine, marketed as the TAE 125-02-99;<ref>{{cite web |url = http://web.thielert.com/typo3/index.php?id=660&backPID=660&begin_at=10&tt_news=863&L=1 |title = Thielert engine in next development stage |access-date = 15 April 2008 |last = Thielert Aviation Engines |date = January 2007 |url-status = dead |archive-url = https://web.archive.org/web/20080511085114/http://web.thielert.com/typo3/index.php?id=660&backPID=660&begin_at=10&tt_news=863&L=1 |archive-date = 11 May 2008 }}</ref> as a result of the engine production change, Diamond began installing the TAE 125-02-99 engine during early 2007.  Although engine displacement had increased, it was deliberately de-rated in order to produce the same power {{convert|101|kW|abbr=on}} and torque {{convert|409|Nm|abbr=on}} as the earlier 1.7 L. engine.<ref>{{cite web |url = http://www.diamondair.com |title = Products |publisher = Diamond Aircraft |access-date = 24 April 2008 |url-status = dead |archive-url = https://web.archive.org/web/20080413231405/http://www.diamondair.com/ |archive-date = 13 April 2008 }}</ref>

In late 2007, Diamond announced it would begin building and installing its own aerodiesels, through a subsidiary, Austro Engine GmbH, in collaboration with other partners that included [[Mercedes-Benz]]. The continued use of Thielert engines on the DA42 was also brought into question following Thielert filing for insolvency in April 2008.<ref name="AvWeb24Apr08">{{cite web |url = http://www.avweb.com/avwebflash/news/MoreTroubleFor_Thielert_197722-1.html |title = More Trouble For Thielert |access-date = 24 April 2008 |last = Niles |first = Russ |date = April 2008 |archive-url = https://web.archive.org/web/20080501103404/http://www.avweb.com/avwebflash/news/MoreTroubleFor_Thielert_197722-1.html |archive-date = 1 May 2008 |url-status = live |df = dmy-all }}</ref><ref name="AvWeb05May08">{{cite web |url = http://www.avweb.com/avwebflash/news/CessnaSuspendsDiesel172SalesDiamondStepsUpSupport_197780-1.html |title = Cessna Suspends Diesel 172 Sales, Diamond Steps Up Support |access-date = 5 May 2008 |last = AvWeb Staff |date = May 2008 |archive-url = https://web.archive.org/web/20080511073907/http://www.avweb.com/avwebflash/news/CessnaSuspendsDiesel172SalesDiamondStepsUpSupport_197780-1.html |archive-date = 11 May 2008 |url-status = live |df = dmy-all }}</ref><ref name="Diamond Says Thielert Insolvency Administrator Is Playing Hardball">{{cite web|url = http://www.aero-news.net/index.cfm?ContentBlockID=6dd57ffd-afc0-4bf4-81dc-823a4ec89292 |title = Diamond Says Thielert Insolvency Administrator Is Playing Hardball |access-date = 24 April 2008}}</ref><ref name="Thielert: How To Kill A Company (Maybe Two)">{{cite web |url = http://www.avweb.com/blogs/insider/AVwebInsiderBlog_Thielert_HowToKillACompany_197956-1.html |title = Thielert: How To Kill A Company (Maybe Two) |access-date = 27 May 2008 |last = Bertorelli |first = Paul |date = May 2008 |archive-url = https://web.archive.org/web/20080526080543/http://www.avweb.com/blogs/insider/AVwebInsiderBlog_Thielert_HowToKillACompany_197956-1.html |archive-date = 26 May 2008 |url-status = live |df = dmy-all }}</ref><ref name="Avweb15May08">{{cite web |url = http://www.avweb.com/avwebflash/news/ThielertCancelsWarrantySupport_197880-1.html |title = Thielert: No Warranty Support For Diamond Diesels |access-date = 15 May 2008 |last = Bertorelli |first = Paul |date = May 2008 |archive-url = https://web.archive.org/web/20080630113652/http://www.avweb.com/avwebflash/news/ThielertCancelsWarrantySupport_197880-1.html |archive-date = 30 June 2008 |url-status = live |df = dmy-all }}</ref> In March 2009, Diamond achieved EASA certification for the rival [[Austro Engine E4|Austro Engine AE 300]] powerplant.<ref name="AvWeb16Mar09"/>

==Operational history==
[[File:Diamond DA42 with Mag Booms.jpg|thumb|A DA42 configured to perform [[aerial survey]] missions]]
Upon its introduction, Diamond had to combat a historic trend of declining light-piston twin sales in the face of increasingly reliable and capable single-engined aircraft for general aviation; the DA42 had only five competing aircraft in its category.<ref name = "fly mag 2015"/>

===DA42 MPP===
The DA42, particularly its use in the surveillance sector, became Diamond's most important business.<ref name = "iraq fi08"/> A dedicated surveillance model of the aircraft, designated as the ''DA 42 MPP'', was developed; during 2008, Diamond delivered 17 DA 42 MPPs and anticipated a demand for between 50 and 60 such aircraft per year.<ref name = "iraq fi08"/> During the latter part of 2008 and early 2009, a pair of [[Royal Air Force]] DA42 MPPs were deployed for eight months to provide combat support to coalition forces operating in [[Iraq]]; during the deployment, these aircraft flew a combined 2,000h in the surveillance role, for which it had been outfitted with Cineflex high-definition cameras, Riegl laser scanners and Scotty satellite communications kit.<ref name = "iraq fi08">Morrison, Murdo.
